SPECIFICATION forming part of Letters Patent No. 252,000, dated January 3, 1882.

Application filed February 8, 1881. (No model.

To all whom it may concern.-

Be it known that we, CHARLES W. DICK- INsQN, of Belleville, and GEORGE RownEN, of

South Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Printing- Presses; and we do hereby declare the follow- I ing to be a full, clear, and exact. description of the invention,such as willenable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to letters of refer ence marked thereon, which form a part of this specification. h

The object of this invention is to print in colors in one continuous process with greater facility and neatness than has yet been done. i It is adapted more particularly to work upon a class of matter such as illuminated. labels, cards, wrappers, and the like, on any grade of paper from a thin and cheap variety to a heavy card board.

The invention consists in the coni'binations and arrangements of parts herein described, all of which will befully illustrated and finally claimed.

Referrin g to theaccompnnyin g drawings,includedin five sheets, in which the sev'eraldetters and figures of reference indicate like parts in each of the figures, Figure 1 is a plan, and Fig. 2 a side elevation,fof the machine as a whole, in whichsaid figures the relative positions-of'the parts are indicated. Fig. 3, Sheet 2,"is an interior side view of a cheek-piece and Figs. 4. and 5 are sections of the same, taken through lines 00 and 3 Fig. 7. Sheet 3, is an end view of the machine, showing. the plunger working in said cheek-pieces; and Figs. 6 and 8 are sectional views of the plunger, taken through line 2 of Fig. 7, looking inthe direction indicated by. the arrow. Said Fig. 6 more particularly indicates the peculiar action of the parts carrying the chase, by which action the printing is accomplished. Figs. 9, 10, and

,11 are views illustrating the parts which operate to carry the paper through the press, Fig. 9 being a sectional view through line to, Fig. l, and Fig.f1l an enlarged sectional view through :20, Fig. 10.

upon the bed-plate B of the machine the cheek- "pieces A, which may be united at their tops by a plate, a, or other connective. pieces are peculiarly formed to carry and guide Said cheekthe plunger by being perforated by the slot 1), (Sheet 2, Figs. 3, 4,5,) in which the plungercarrying beam 0 works, in a manner more fully described hereinafter, and by having the interior faces thereof each correspondingly traversed by the peculiarly-curved grooved, adapted to receive the chase-plate guide e, which in the case shown is a wheel working upon an arm, f, rigidly secured to the chase-plate shaft 9. The said interior surfaces of the cheek-pieces are further grooved by the vertical tracks h, with which the plunger bed-plate i engages. Grooves or sockets j are also formed, as shown in said Fig. 3, for the reception of the sliding plates is, the object of which will hereinafter beexplained. These last said grooves or sockthe cheeks, in which are placed springs m, having their upper extremities secured in the upper portion of said groove 1 to the cheek-pieces 'A, and the lower ends fastened to pintles 71. upon the said plates k, which pintles a project outward into the said exterior grooves, l. The cheek-pieces may be formed of one solid plate having the several grooves above mentioned therein, or they may, for reasons of convenience while in course of construction, be formed of separate plates, as in Fig. 5, the same being joined together by bolts or otherwise. The cheek-pieces may be secured to the bed-plates by having flanges 0 formed thereon adapted to receive bolts, and; by that means secured to the bedplate, as shown; or any other usual method may be employed for accomplishing the same result.

Between the checkpieces, upon the tracks h therein, works the plunger bed-plnte-i,having the vertical motion necessitated bysaid tracks. Said plunger-plate i is secured to the carryingbeam 0 by the tie-plate p, the ends of which are embedded in side portions of theplnnger-plate, as shown. The beam 0 receives its motion from the connecting-rod g, which receives it 7 7o ets have communication with grooves 1, Figs.

2, 4, 5, formed within the exterior surfaces of through the crank r, cog s, pinion t, and driving-pulley'a, each successively from the main pulley and shaftin g o.

Chase-plate shafts g are secured upon the plunger-plate i in such a manner as to allow the same to revolve or rock therein, the said plunger-plate being constructed so as to form bearings b or boxes for the pivotal ends of said shafts 9. These said bearings may be either constructed homogeneously with the plunger-plate t or may be attached thereto by any of the well-known means. The plunger bed-plate i may also have secured thereon or integrally formed therewithbea-ringsc for the chase-plate shaft 9, so arrangedas to resistthe pressure of the chase upon the platen e. v

The action of the-parts described is substantially as follows: The power is transmitted *from'the, main shafting v, Figs. 1, 2, and 7,

through the driving-pulley a, pinion t, cog s,

"to the crank r, by which and the connectingrod q simple rotary motion is changed to veriical motion, as will be readily understood by reference to said figures. The plunger-carrying beam 0, actuated by the connecting-rod q,

' brings the attachments connected therewith into regularly-repeated contact with t-heplaten,

as follows, reference'being had more especially to Sheet 2, Figs. 3 and 6. The downward stroke of the beam 0 causes the chase-plate guide e, operating in the curved groove d, to

' change the direction of its passage, as will-be clearly understood, and by that means to rotate the said chase-plate sha t g, turning the chase-plate a from its'former vertical position to a horizontal. In this action the arnisf, which are rigidly secured to the shaft g, act

as levers, the guides e acting as the powers "which swing the chase-plate shaft as desired.

When the chase-plate a isthus in its horizontal position the back of said plate will bear against the bottom surface of the plunger bedsition at a point considerably above the platen.

, We have th eret'ore so arranged and constructed. the machine as that the chase-and type there-' in contained, after reaching the before-mentioned horizontalposition,will be brought down squarely upon the paper, as follows: After turning the angle the guides a strike the sliding plates 70. The upward tension of the sprin s m upon said plates keeps the chase-plate hard against the bottom surface of the plunger bedplate, as in the manner before stated; butthe continued downward action of the 'beam c forces the sliding plates downward until the type come into engagement with the paper. At thispoint the crank passes thev center of motion, the beam 0 moves'upward, and the above-mentioned operations are reversed and repeated at will.

It will be seen from the drawings that two horizontal position. its downward motion the projecting plate d the impression is made. andtype rise the action of the springs upon the type, however, has no connection with my present application. After the first impressionbythedouble plates,mcchanism,whiohwill be hereinafter fully explained, is applied to the paper, which causes said paper to travel forward a-given distance while theplunger passes upward and returns. Upon the second application of the type to the paper the first plate will give a second color to the second form of printedinatter, (first impression,) while the second plate will give a new form, the plunger again rises, the paper passes another given distance, and the process is repeated, the first plate or chase of type giving a second color to theformpreviously printed by the second plate, this process being spccessively repeated by a continuous process. The type, being covered with viscous ink, is very apt to draw the paper fromthe platen on its upward motion, and thereby disarrange the same for a second impression. To obviate this I form a deep slot in and across'the bottom of the plunger-plate i,.parallel with the beam 0, and into the said slot a steel plate, 11, is placed. Upon said plate d are secured rods l at convenient and appropriate distances from one another, two or more being preferable to one, although one may accomplish the work. Said rods pass up into holes or recesses f, which are adapted toreceive springs g, as shown. Said springs bear against the beam 0, and are secured to the rod or rods at a point near the plate d. It will thus be apparent that the plate d will have a tendency to project downward from said plunger-plate between the chases when the same are in their When the plunger is in will evidently first strike the paper. 'Upon the continued downward action of the plunger the said plate (1 willpass up intothe out until When the plunger the platestill hold the said plate into engagement with the paper, holding said paper firmly upon the platen until the type are entirely clear from thesaid paper, thus effectually preventin g the di'sarrangement above mentioned.

It is obvious that, should we desire to print in three, four, or more colors,'the same may be accomplished by additional mechanisms similar to those described comprising our invention, being built upon the same bed-plate and operating in connection therewith.

In printing by means of our invention it is necessary to draw the paper across the platen by a regular succession of movements and stop- 1 pages, as before intimated, the latter to allow the impressions to be made. "This is done as IIO follows, reference being made particularly to.

Figs. 1, 2, audit); The paperlisdrawn from its original roll 9 through and by means of the feed-rollshk'. Itisthen'drawnover theplaten c bythe feed-rolls m a, the former,m, being? hutsmall friction-wheels adapted to catch the edges of thepaper away from the printed portion to obviate smntting thenewly-printed matter thereon. It is obvious that the feed-rolls lc and a should be precisely the same diam eter in order to draw the paper uniformly through the machine. The succession of movements of the paper above referred to are produced, by the cam 0 operating ratchet-wheelp, connected with the feed-roll a. Said cam 0 receives its rotary motion from the shaft g, which carries the cog s and crank 1' through the train of cogs r s t. Said canto (while the crank r is producing the upward stroke with the rod (1 and beam 0) raises the lever a. This in turn raises the sliding rack 22'. Said sliding rack has teeth formed thereon to engage with the pinion 2, having rigidly secured thereto a pawl-arm, 3, which carries the pawl 4 to engage with teeth on the ratchet-wheel p.

The last-mentioned parts operate as follows:

While the plunger-beam and connecting parts move-upward and free the paper from the type the can] 0 raises the lever to and rack a, turning the pinion 2 and pawl-arm 3, bringing the pawl 4 hard against the teeth on theratohetwheel 19, turning thesaine, and consequently rotating the feed-roll a, which carries the paper forward. 0n the return motion of the cam (and while the mechanism connected with the plunger is printing) the lever 20 and rack o fall and the pawl slides over the teeth on the ratchet-wheel preparatory to taking a new hold, the feed-rolls and consequently the paper remaining at rest, as will be clearly understood by reference to Fig. 2. To regulate the distance that it is desired that the paper should travel, we have attached to the bed-plate B, beneath thelever u, a set-screw, 5,which allows said lever a to fall but the desired distance,

and consequently the cam 0' can operate the pawl to but the amountof play remaining. The feed-rolls nand 7c are connected by belting 6, which runs upon pulleys 7 and 8. Said I pulleys have fast connection to said feed-rolls and revolve with them. Therefore when said pulley n! rotates under the influence of the cum 0 the said feed-roll It makes a corresponding motion. Thus the thinnest or lowest grade of paper can be printed upon from off a continuous roll without any danger of tearing-a new and useful feature of improvement never before accomplished, as far as we are aware.

As a substitute for the pulleys 7 8 connected by belting, we can construct a ratchet and pawl corresponding to the one already described I upon the feed-roll k and connect the pawl arm thereof (which would correspond to pawl-arm 3) with the said pawl-arm 3 bya rod. By this device unity of action of the rolls would like wise be prod need.

The tension of the Sl(l6f69d-1Oll8,7ll', may be suited to the thickness of the paperby set- I the carriages 11, as shown. To suit said rolls mto any width of paper the said carriages 11, to which the trucks 10 are pivoted and in whichthe set-screws 9 are held, slide laterally upon the shaft 12, and are secured in the position desired by the set-screws 13.

After the printed paper passes from the feed-rolls m n it undergoes theprocess of being cut into the sizes desired, a portion of the mechanism being shown at J, but which mechanism will form the subject-matter for another subsequent application.

In conclusion, the process which the paper passes through incourse of being printed upon by our device is as follows: It passes from the original roll through feed-"rolls it It. The former, 11., maybe a wooden roll covered with can ton-flan nel or other compressible substance, which equalizes the pressure of the paper against the roll is, which is necessarily hard and unyielding. The paper then passes over the platen, stopping at regular intervals to be impressed by the type held in the chasevupon the chaseplatea. When the impressions are made in the manner hereinbefore explained the plunger and connections rise and the 'paper is drawn forward by the roll n, actuated by the ratchet and pawl and connections. The

paper receives the first impression of color from the plate nearest the original roll 9, then in due course of operation passes under the second plate, receiving the second color, and so the third and fourth colors, should the machine be so constructed.

'I am aware that an intermittently-acting feed-roll has been used in connection with printing-machines, and that it is not new to arrange two sets of feed-rollers with the printing mechanism between them, and therefore I do not claim these features, broadly.

Having thus described our invention, what we claim, and wish to secure by Letters Patcut, is
